Research ArticleOpen accessIn the abstractA Novel Interconnect Structure for Elmore Delay Model with Resistance-Capacitance-Conductance SchemeUma Ramadass, Krishnappriya, Jebashini Ponnian, P. DhavachelvanIn this brief, we present a simple close-form delay estimate, based on first and second order moments that handle arbitrary voltages and conductance effects for a lumped and distributed line. This proposed model introduces a simple tractable delay formula by incorporating conductance (G) into Resistance, Capacitance (RC) network by preserving the characteristics of the Elmore delay model. The RCG model … …American Journal of Applied Sciences, Vol. 10, Issue 8 · 24 Jul 2013 · 7,054 accessesView PDFCite
Research ArticleOpen accessIn the abstractTHE DYNAMIC NONCE BASED AUTHENTICATION SCHEME TO DEFEND INTERMEDIARY ATTACK FOR WEB SERVICESElangovan Uma, Arputharaj KannanNowadays, Web services have used drastically for various online applications like banking, e-bill processing. All online services need robust security architecture for handling sensitive data like user name, password. But, The Web service has security problems that need to be solved. The existing security scheme lacks to defend the attacks from replay and password guessing attacks. In this study we … …Journal of Computer Science, Vol. 9, Issue 8 · 4 Jul 2013 · 6,855 accessesView PDFCite
Research ArticleOpen accessIn the abstractON-THE-FLY KEY GENERATION FOR AN EFFICIENT ROAD SIDE UNITS BASED AUTHENTICATION IN VEHICULAR NETWORKSAshraph Sulaiman, S. V. Kasmir Raja, Sung Han ParkObtaining efficient security without compromising privacy is a primary issue in vehicular communication. Though many counterparts proposed solutions in this regard, accommodating scalability, security and traceability altogether is a difficult task due to the contradictions between these qualities. Some of the previous studies suggests RSU based authentication to address the above issues, while others propose independent OBU authentication. In either … …Journal of Computer Science, Vol. 9, Issue 8 · 4 Jul 2013 · 6,882 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Enhanced and Cost Effective Group Key Management Scheme for Multicast NetworkSaravana Kumar Muthusamy, Purusothaman Thiyagarajan, Lavanya SelvarajKey management plays a vital role in the data communications. The proposed scheme is a key management scheme that provides more efficient and secure methods for key generation and utilization. Enhanced and cost effective key management scheme achieves a secure communication between the members within the group-based network. In this scheme, the group key is generated only once which is … …Journal of Computer Science, Vol. 9, Issue 4 · 10 May 2013 · 6,395 accessesView PDFCite
Research ArticleOpen accessIn the abstractMultiple-Input Multiple-Output Transmission Over a Multipath Faded ChannelsI.A.Z. QatawnehThe use of multiple antennas at the transmitter as well as at the receiver can greatly improve the capacity of a wireless link when operating in a rich scattering environment. In such an arrangement all transmitting antennas radiate in the same frequency band so the overall spectral efficiency becomes very high. Such a multiple antenna scheme, popularly known as Multiple … …American Journal of Applied Sciences, Vol. 10, Issue 3 · 11 Mar 2013 · 6,420 accessesView PDFCite
Research ArticleOpen accessIn the abstractMultichannel Cognitive Cross Layer Optimization for Improved Video TransmissionMeenakshi Murugappan, Manimekalai Thirunavukkarasu, Maneesha S. MohanMultimedia applications particularly real-time video transmission in wireless networks, envisions end to end user perceived video quality as an important QoS parameter to be achieved. Cognitive Radio promising efficient spectrum utilization combined with Cross layer optimization is seen as a powerful combination to achieve the desired video quality. This study proposes Optimal Channel Sensed Multichannel Cognitive MAC (OCSM-CMAC), a QoS … …Journal of Computer Science, Vol. 9, Issue 1 · 6 Feb 2013 · 7,202 accessesView PDFCite
Research ArticleOpen accessIn the abstractPrivacy Preservation for File Sharing Scheme Using Secured File Block ID with Binary TreesM. Balamurugan, S. Chenthur Pandian, J. BhuvanaPrivacy, the security of information from unauthorized access is gradually needed on the Internet and yet progressively more important while each user acts as both consumer and producer. The lack of privacy is mainly employed for peer-to peer file sharing applications, in which users in the network shared file with each other and their actions are easily monitored by the … …American Journal of Applied Sciences, Vol. 10, Issue 1 · 1 Jan 2013 · 6,935 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnhanced RSACRT for Energy Efficient Authentication to Wireless Sensor Networks SecurityP. Kalyani, C. ChellappanProblem statement: The Security in WSN has become a challenge because of its inherent limitations of resources imposed on the sensor nodes. Authentication and key management scheme allows WSNs to be used with confidence and maintains integrity of data in sensor networks. Approach: In the WSN limited resource scenario the generation of public key done and are randomly pre distributed … …American Journal of Applied Sciences, Vol. 9, Issue 10 · 18 Aug 2012 · 7,344 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Survey of Intrusion Detection Schemes in Wireless Sensor NetworksMurad A. Rassam, M. A. Maarof, Anazida ZainalWireless Sensor Networks (WSNs) are currently used in many application areas including military applications, health related applications, control and tracking applications and environment and habitat monitoring applications. The harsh and unattended deployment of these networks along with their resource restrictions makes their security issue very important. Prevention-based security approaches like cryptography, authentication and key management have been used to protect … …American Journal of Applied Sciences, Vol. 9, Issue 10 · 17 Aug 2012 · 8,738 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Policy Based Scheme for Combined Data Security in Mobile Ad hoc NetworksL. Kartheesn, S. K. SrivatsaProblem statement: In Mobile Ad hoc Networks (MANET) routing protocols, we require a network-level or link layer security. Since without appropriate security provisions, the MANETs is subjected to attacks like network traffic, replay transmissions, manipulate packet headers and redirect routing messages. In order to address these needs, a policy based network management system that provides the capability to express network … …Journal of Computer Science, Vol. 8, Issue 8 · 6 Aug 2012 · 6,725 accessesView PDFCite
